Wilden® P420/430 and P820/830 FIT Metal Pumps Now Available

by PSG | Oct 02, 2017
Wilden-P420-P820-FamilyGrand Terrace, CA — October 2, 2017 — Wilden®, part of PSG®, a Dover company and a worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to announce the availability of its P420/430 FIT 38 mm (1-1/2”) and P820/830 FIT 51 mm (2”) AODD pumps equipped with the Pro-Flo® Air Distribution System (ADS). Available in three wetted-path materials of construction – aluminum, stainless steel and ductile iron – the new P420/430 and P820/830 FIT pumps feature bolted product containment, easier maintenance and efficient operations.

Providing increased performance with no repiping necessary, Wilden FIT pumps have been designed to be direct replacements for existing Wilden clamped pumps, bolted pumps and competitive models. For simplicity of installation, direct replacement means that FIT pumps fit bolt-to-bolt and pipe-to-pipe in existing fluid-handling piping systems. This makes the Wilden FIT pump an easy, cost-effective way to enhance and upgrade existing pump performance with superior bolted product containment.

The bolted configuration of the P420/430 and P820/830 ensures total product containment while the redesigned liquid path reduces internal friction to maximize output and efficiency. Wilden P420/430 and P820/830 FIT pumps offer the longest mean time between repair (MTBR), superior anti-freezing and increased on/off reliability. These pumps are also shear sensitive and intrinsically safe with self-priming and dry-run capabilities.

Wilden P420/430 and P820/830 FIT pumps feature maximum discharge pressures to 8.6 bar (125 psig), and the maximum flow rate on the P420/430 is 492 lpm (130 gpm) while the maximum flow rate on the P820/830 is 609 lpm (161 gpm). Diaphragms are available in Buna-N, EPDM, Polyurethane, PTFE, Saniflex, Viton® and Wil-Flex.
